- Copy the header value and paste it into your API client or curl command for testing.
Frequently Asked Questions
- Is Basic Auth secure?
- The credentials are only Base64-encoded, not encrypted — Base64 is trivially reversible. Always use Basic Auth over HTTPS to protect credentials in transit.
- How do I use it with curl?
- Copy the header value and pass it with: curl -H 'Authorization: Basic value' https://api.example.com. Alternatively use curl's built-in -u username:password flag.
- Is processing done in the browser?
- Yes — everything runs locally. Your credentials are never sent to any server.
